1)
Check if the power switch is closed.
2)
Make sure there is power for input cable.
1)
The current potentiometer fails. Replace it.
2)
Check if any loose contact exists inside the machine, especially

1)
Check if any poor contact exists inside the machine.
2)
Open circuit or poor contact occurs at the joint of output terminal.
3)
The abnormity indicator is on.
A.
The machine is under over-heating protection status due to long
time operation. For this situation, it is unnecessary to unplug the
power plug so that cooling fan can continue to cool down the
welder. Welding can be continued after indicator is off;
no
B.
Check if the thermal switch is ok. Replace it if damaged.
C. Check if the thermal switch connection is under good contact.
D. It is possible for welder to be under over-current protection status
if indicator is on for a long time. For this situation, please do not
restart the machine, but contact local agent for professional
assistance.
The rated current of the electrode holder is lower than its actual working
current. Replace it with a bigger rated current.
